How to become a Plumber
Almost every plumber you'll meet learned the trade by getting paid to carry pipe for someone who already knew it. School can help, but the apprenticeship and the license are what open the door. Here's how people actually get in, and what the contractor reading your application is looking for.
Four ways into the trade
Union apprenticeship
Your local plumbers and pipefitters union runs a registered apprenticeship with classes at night and full-time work on job sites during the day. You apply, take an aptitude test, sit an interview, and wait for a spot. The wait can be long and the application window may only open once in a while, so find out when your local takes applications and don't miss it. Once you're in, you earn while you learn, and raises come on a set schedule.
Open-shop apprenticeship with a contractor
Plenty of non-union shops sponsor apprentices through contractor associations or a state-registered program. You call shops, walk in, or answer a helper posting, and the owner signs you up once you've shown you'll show up. This is the most common route for people who want to start working right away instead of waiting on a union list.
Trade school, then a helper job
A plumbing program at a community college or trade school teaches code, blueprint reading and the basics of soldering and threading pipe. It won't replace an apprenticeship, but it gets you hired as a helper faster because you won't need to be shown what a P-trap is. Check whether your state lets school hours count toward the apprenticeship before you pay tuition.
Maintenance or military background
If you've done building maintenance, facilities work or a utilities role in the service, you already know your way around valves, pumps and fixtures. Say so plainly on your application. Shops still want you in a registered apprenticeship for licensing, but you may move up the pay steps faster and get trusted on service calls sooner.
The license sits at the center of all of it
Plumbing is licensed work in most places, and the rules are set by your state, and sometimes by your city or county. The usual path runs from registered apprentice to journeyman to master, with required hours on the job and a written exam at each step. Some areas also want a separate license for gas piping or backflow testing. Don't guess at your local rules. Look up your state plumbing board or licensing office and read their requirements before you pick a program, because the hours only count if they're logged the way the board wants.
The work itself is physical and it isn't always clean. You'll crawl under houses, work in attics that feel like ovens, and snake drains nobody else wants to touch. On-call weekends are part of the deal at most service shops. The people who last are the ones who don't mind that and like solving a problem with their hands.

Questions people ask
Do I need to go to trade school to become a plumber?
No. Most plumbers learn through an apprenticeship, and many never set foot in a trade school outside the classes their program requires. School is useful if you know nothing about the trade and want to walk into a shop sounding like you do. If money's tight, get hired as a helper first and let the apprenticeship carry you.
How long does it take to get a plumbing license?
It takes a few years of logged work and classroom hours before you can sit for the journeyman exam, and more time after that for a master license. The exact hours and exams depend on where you work, so check with your state plumbing board. Keep your own record of hours, because a lost log can cost you months.
Is service plumbing or new construction better for a beginner?
New construction is easier to learn on because the work repeats and a foreman is usually nearby. Service plumbing teaches you faster and tends to pay better once you're good, but you're alone in a customer's kitchen with a leak and no one to ask. A lot of people start in construction, then move to service once they can diagnose on their own.
